The Month Spring

The Weather

 

The last spring snow melted in the gardener's lot the night of May 10th. It will now be in the nineties.

The Farm(s)

On the ninth, I had a moment to look on the garlic, strike the weeds with a hoe. Never before have I seen the garlic so small so late.

The effervescence of lambsquarter and thistle is contained with mats of semi-wet straw remaining from last fall.

The Greenhouse

Three rows by five of ear leaved brome, Bromus latiglumis, out front of 4 rows of bottle brush grass, Elymus hystrix, and three rows of silky wild rye, Elymus villosus. An ability or want to grow in the shade is a commonality among these monocotyledonous Poaceae. These will likely be established on the culvert embankment, partially collapsed last fall, once restored.

It takes an especially observant person, and some years of experience, to decipher one seedling's visual cues from another. Identification -what is that? Dicotyledonous plants, with pubescent stems and leaf edges, slightly wavy heart-spade shaped leaves, pale green, growing thickly (indicating small seeds to the planter of seeds). This blindness to leaves and stems, the miniature, and impatience allows many undesirable plants to survive the hoe.  Refining possibility by my seed order leaves only Campanula americana, or Tall Bellflower. When I return from Cedar Creek, the tag will tell how experienced I am.

Blue lobelia, Lobelia siphilitica, whose seeds are only a fraction of a millimeter, have a stellar germination rate. Competition must be the thinning mechanism.  These seedlings are for the northern edge of the great swamp, that two acre depression of drowned trees, duckweed, and fluctuating water levels toward the back of our woods. On that partly shady slope -weedy garlic mustard, thistle, canary reed grass and me. I've got black plastic on part of the water's edge covering canary reed grass, and been hoeing then planting Iris versicolor, spotted joe pye weed, blue vervain, big blue stem grass, and others. The seed bank of garlic mustard and root network of thistle is deep, while canary reed grass forms dense, fibrous mats that are bears to pull, but there is also a surprising amount of diversity in this highly disturbed site at the edge of a former commercial gravel pit.

Ephemerals

Hepatica, Anemone americana, trailside, Cedar Bog Lake trail, May seventh Cedar Creek Ecosystem Science Reserve.

Large flowered bellwort, Uvularia grandiflora, like many ephemerals growing in our woods, had a prolific season. Is this is due to winter weather resembling winters these plants have evolved by? Last year, after yet another overly warm winter, I stumbled upon one, maybe two bellwort. This spring there are possibly dozens of clumps scattered in previously barren understory sites. Our only known patch of trillium, nibbled by the hungry deer this spring, now has peers. A display of randomness that throws off any rational sense of seed distribution and opens us to the potential of seeds storing in ground until conditions are right, to a migration of seeds via ants and mice, and, as is the case with trillium, to the slow process from fruit to flowering plant. A warming climate, should it create a warming winter here, won't be hospitable to these spring ephemerals, more likely favoring the weedy plants that take advantage of disruption and do not have such particular requirements for germination.

Nodding trillium, Trillium cernuum.

 

Great Garlic Pull

On of the chores of April and early May is the great garlic mustard removal. Last spring I pulled thousands of plants, only to be dismayed to see so many more in fall, quite possibly more than I had cleared. Pulling only created opportunity for new first year seedlings to make a strong showing. The muddy soil clung to my shoes, transferring seeds to new areas; tossing pulled plants also transferred seeds to new areas. And surely animals, other than me, moved seeds along on their feet or hooves.

This year, we have a new tack, built on observations and learning. First, we have divided the woods into zones. It is an idea I formed a few years back when volunteering in Prospect Park -namely that parks employees should not be responsible for tasks, but carrying out maintenance responsibilities in zones. The idea was built around the notion of ownership and responsibility, but I digress.

We will not tackle the highest population density zones first, but last. I have observed that the dense populations compete with themselves. If not pulled, seeds will not travel too far, especially if I weed whack the flowering stalks before seed development because the newly sprouted, post cut flowering stalks will not be as tall or vigorous. Keeping the low density populations clear will give a feeling of success and be a front line against spread. Native plants can be planted in those zones to help create ground cover.

Last spring I gave spot treatment with a glyphosate spray. I was completely dissatisfied with the results. Not only did many of the plants still go to flower despite having been sprayed weeks before, I ended up pulling them anyway. If I sprayed too early (early April), the plants were not actively growing enough for the spray to have an effect. From now on I will rely on other methods.

Garlic mustard seedlings growing in a pile of buckthorn, Rhamnus cathartica, saplings pulled last spring. The seeds are everywhere, and the mere act of pulling the plant (or any plant) will help sprout new garlic mustard. Underneath every 2nd year stand of garlic mustard are hundreds or thousands of seeds and seedlings waiting for their chance.

One of the prime benefits of pulling garlic mustard, which is nearly everywhere, is the opportunity to see what is growing off trail. Here, along the shady edge of slope of the little wetland I found evidence of an enlarged colony of fern. We have only so much fern in our woods, most along the shady and wet northeastern slope, and I'd like to see much more. Did my work last year enable these fern to gain some ground?

A reason to dedicate so much time to limiting the spread of garlic mustard in our woods is Uvularia grandiflora, Large-flowered Bellwort. It is a rare treat that never seems to be in the same spot twice. Undoubtedly, I will be here next spring to pull the garlic mustard you can see behind it, but will the bellwort?

Dicentra cucullaria, Dutchman's Breeches, native to the region, but not found anywhere within the bounds of our property. This singular plant was brought over from the woods on the southwest side of our great wetland last spring and, with great fortune, had survived the hasty transplant. I gather that this used to grow around our woods but had been out competed or trampled by cows or people. Behind the dicentra are ramps, Allium tricoccum var. burdickii, a type of bedstraw (weed or not?) and a few seedlings of garlic mustard (I did just pull the 2nd year plants).

On the shady north facing slope where little else grows but sugar maple and garlic mustard, a rue, likely Early Meadow, but time will tell. Update: probably Blue Cohosh, Caulophyllum thalictroides.

Wood Anemone, Anemone quinquefolia, surrounded by garlic mustard and some buckthorn saplings  in a tree-fall clearing. This zone has to wait as it is rapidly becoming a dense stand, there is tree work to be done, and is difficult to navigate.

Colonies of Cardamine concatenata, Cutleaf Toothwort, are more charming than the swath of garlic mustard I cleared a few days ago.

Not far from the patch of fern, this low growing plant is coming up in what appears to be a fairly broad colony. It is not Stinging Nettle, Urtica dioica, however, a plant I could expect in this wet area but rises in denser mounds and with just a bit less shade tolerance. Another to watch as the garlic mustard season progresses.

Clearing is the first line of defense (or offense?), but of course, we also eat our share.

This area was completely cleared last spring.

But two people cannot possibly eat our way out of this much garlic mustard. 

Of The Many Signs Of Spring

 

The birds are back, big and small, and the weather a swinging ride. Mid seventies two days ago, last night a snow fall. Garden garlic is popping up, early varieties first. Ticks are up and about in the weedy reaches of the woods and the chorus of frogs singing every day, but this one. Ramps are up as well as some unwound bloodroot.

I have a rapidly thickening list of projects to tackle, the least of which is garlic and lawn's corn meal (nitrogen), lawn seeding where it had been turned to mud last year by heavy equipment, till, add compost, and plant potatoes received from Seed Savers, plant the native seeds stratifying in the fridge, chainsawing, chainsawing, chainsawing.

There is so much garlic mustard in the woods you'd think I didn't pull thousands of plants last year. I've tried to enlist the local scouts to help this year, but I have yet to hear back. There is much much much buckthorn, and I am blazing a new trail to get around the permanent inundation in the back slough, a trail that opens up the cedars and an unusually placed, young apple tree. There are bridges to repair or replace in every corner, all which will find their way onto the business page.

I have three or four or five art projects running. Just came back from New Mexico where I was making images of space over the border, another dealing with athletic fields, yet another of artists situated in landscape, and of course, Phenology.

The Woods Today

Back in NYC I might take a walk from time to time, but more often than not it was for the purpose of getting somewhere that I might find myself on a walk. Today, after gaining some ground on research for my (other, new) summer course Shipwreck of the Minotaur at the Mayapple Center for the Arts and Humanities, I chose to take a walk through the woods with some purpose in mind, but mostly to get out of doors for an hour. I did need to check on the sap buckets, as cooler weather has extended our sap season, and also to check on my Easter day's garlic mustard eradication project around the back slough.

I've kept my eye on the Tradescantia spp. that I transplanted from Brooklyn last year in a new garden where the old lilac used to dwell. It looks to have survived. The same garden is now home to the old Brooklyn 'New Dawn' climber rose (a rose that has seen four different yards over its years), a sedum I found growing here in the woods, Dicentra eximia from Brooklyn too, and whatever else was growing there that we've decided to allow (and hopefully not that horseradish I did my best to dig out).

In the front yard, all varieties of garlic are now soaking up the sun. Incidentally, these are not German Hardy, but an artichoke variety, possibly with 'giant' in the name, that were shipped gratis, likely because of poor size thanks to drought and fire in the garlic seed producing region. There are as many commas in that sentence as garlic in this row, but my point is that the sign is a stand in.

I headed into the woods, although the wind made for a biting chill and a hazardous walk through the ready-to-fall. So much dead wood squeaking and creaking like a brig on the open seas, I hesitated to pause for the earliest of ephemerals like Virginia Waterleaf, Hydrophyllum virginianum or the mystery plant, below, that caught my eye as I hiked off path to navigate a significant enlargement of the water line in the back slough.

I was motivated to get back to the slopes of the slough to check on the garlic mustard that I chose to spray with a low percentage mix of glyphosate and water last Sunday. Spring is the time to deal with garlic mustard, particularly March and the earliest of April. Virginia Waterleaf, ramps, some rosa species, a few asters, and other early, less pernicious weeds are coming up and I have no desire to affect those in the act of ridding the woods of garlic mustard. In these zones hundreds, probably thousands, of garlic mustard seedlings are sprouting from the seed bank. It was not an easy decision to spray, especially within a yard of the slough's water line. And I am frustrated to report that after six days the results were not significant. Most leaves were mottled, but the plants were not in the state of distress I would have expected. I've considered that I may need to apply a second course, although I am not happy about that. It was necessary to do so, even with a much higher percentage of glyphosate, on the buckthorn "hedge" growing alongside the garage pad. What I have to consider is the compression of the wet soil in spring. It appears to me the less foot steps, the better, especially after the frost heave has done such a nice job of loosening, aerating, and draining the soil surface.

In the past I thought garlic mustard didn't do well in flooded soil, and maybe it won't if the slough remains flooded. However, what I've seen is that in early spring the ice melts and freezes and this heave extracts the garlic mustard from the mucky soil. It then floats, roots and all, in the spring melt water, preserved in a cool water bath until conditions improve. At the water's edge the leaves and stems of garlic mustard are bluish gray to the deepest purple and often hard to spot against the dark water. The garlic mustard a foot or two away, on drier land, have some purple to the stems, but the leaves are quite green. So green, in fact, that it is a little painful to pull or spray at this time where you find yourself longing for the green of spring.

So what happens to this water's edge garlic mustard? Does it die? I don't think so. Many of the plants, some of which I simply scooped out of the water and some which were easily pulled from the muck, had the biggest roots. Garlic mustard is a biennial, so last year the seedlings emerged and grew strong, despite the waterlogged soil, and this year they are ready to grow and set seed. I'm not willing to wait for the sake of observation, yet I am sure many will escape my vision or reach, and I will be a witness to their success.

As I make my way around the slough, eyes to the ground, I think much about what good the garlic mustard could be doing. What species make use of it for cover or for food? Does it stabilize the soil on the wooded slopes? Is balance achievable? Is garlic mustard simply symptomatic of a woods so degraded by other culprits (err, humans, for instance)? In other words, how necessary is the work I've begun, and am I causing more harm than good? And, you know, I like questions.

Winter Mind

Winter has finally come to us. Temperatures below 20 degrees F, snowfall, car doors frozen shut with the last freezing rain, the clinkeling of ice crystals shed at forty five miles per hour. Despite this wintry attitude, we here at PrairieWood have work to do. The new shop is now standing with roof and ceiling. It never occurred to me that I would work into the night, outdoors, at just a handful of degrees above zero, but I did just that last Sunday so that we could get the wiring in before the ceiling closed out our access.

While I've been able to put most house projects on hold until springtime, one thing is still weighing heavily on my mind -the woods. What once went concealed by countless leaves is now made obvious by the contrasting wet bark and newly fallen snow. If I could sum up its appearance in one word, it would be diagonal. What is it about a wood of slanted trees that is so disturbing? Is our sense of order satisfied by horizontal ground and vertical columns of trees? Is the removal of angled wood a goal of a "clean" woods? 

What we need here is a plan, a forest plan, to guide us in the care of these woods. But wait. Why do the woods need our care at all? Isn't that awfully anthropocentric? Couldn't the woods take care of itself as it has for thousands of years?

Why is it so hard to look at the woods and see ourselves in it? We entertain the woods as a medium of passage. We experience the woods, but are not a part of it. Our aim is to be out-of-the-woods. We are beasts of clearings where a few selected trees may stand sentry. Why not the woods? Is it a blow to our ego to be among such large beings? Or is it the inherent danger of a sustained presence in the woods, the mashup of life and limb? Maybe this is the most practical tack, that a life in the woods is a life fraught with falling timber. Even among the trees there is danger. No elderly tree gives way without taking or scarring those around it. The falling of a great old tree reverberates through the forest, destroying the order, remaking communities, providing opportunities for well placed upstarts. 

I've realized how easy it is to make a metaphor of the woods, but the questions are more difficult. In our short time here we've had to ask many, and no answer is quite right. Any intervention is yet another question, or string of questions. We cannot extract ourselves from the story of the woods; people created it and we are living it. 

I regret to speak so abstractly, but somewhere in this line of thinking is a better perspective that may be teased out in writing. I understand intuitively that we have a role in this mess, that we are the aliens among the trees, roadsides, and fields. We cast dispersions on the plants and animals that take advantage of sensitive niches, but were it not for us this would hardly be the case. We are the aliens, the agents of drastic change. We project it onto others (plants, animals) while claiming our place. There would be no buckthorn, no garlic mustard, no barberry or burning bush if it weren't for our own invasive nature. Can we make it right? Can you take it back? Can you undo the done? 

This is a defining aspect of our culture. We invade a place, instigating the consequences that we see all around us and then tell ourselves that it is the others' fault, it is their doing that has created the mess and maybe, just maybe, we'll commit resources to cleaning it up, and it will be ongoing, forever perhaps. The productive citizen looks away; it's just easier that way, isn't it? We can spend a life throwing resources at a problem that traces back to exactly where we stand. Is it rational to label plants and animals invasive and yet completely ignore our responsibility for it? 

In the woods I see the paradigm of our conflict, one as much with the natural world as it is with other human beings. I am left asking you if an answer, one that can never be fully right, is to look away or to commit the resources to try to correct the damage, forever, perhaps. And what to make of the trying, because trying isn't necessarily accomplishing anything other than assuaging one's conscience of total responsibility. 

I don't mean to be melodramatic. It's simply that so much of what appears to ail us today is hindered by our unwillingness to take responsibility, or at the very least, to understand our responsibility. I am not personally responsible for the rampant buckthorn in the woods, but I sure can see how it came to pass and how I've benefited from our ancestral migration to this place. 

Ignorance (in the sense of not knowing, but also ignoring) leads to bad decisions, or self-centered ones, and consequences difficult to ameliorate. For instance, water holds in the middle swale, in the back woods, and leads to ponding, mosquitoes, and to water-logged roots which can bring an untimely death to the trees there, fallen timber, more sunshine, and then faster buckthorn spread. I considered trenching a drainage so that the captured water could drain into the great wetland. Autumn came and I saw that some trees at the center of the middle swale remained green-leafed long after the rest went yellow.

Upon investigation, the bark and leaf, below, spoke. These are silver maple, Acer saccharinum, the fast growing, brittle-wooded tree of wet areas in the Eastern Forest.

I can only guess that silver maples living at the boundaries of its range put the species under pressures not necessarily found near its core. So I came to an understanding of this middle swale. I will not dig a trench to help drain it, yet I will dig deeper into what else is growing, and dying, in this area, and attempt to understand it before acting or, quite possibly, not acting at all.

The questions of how to act and what sustained gestures are both possible and effective, are for our winter mind. What can be done that limits the rampant buckthorn and doesn't undermine the fragile species under threat from its able fecundity? We spent a quantity of time pulling garlic mustard from the drainage stream connecting the northern, small wetland to the great, southern wetland. Our work was effective, but it also appeared to me that there was a significant reduction in jewelweed in the very same area. I'm working on memory, now, but I thought it was more prolific in that region in past years. So I wonder, was it the garlic mustard that reduced the jewelweed population to nearly zero, was it natural swings in population due to unusual temperatures or flooding, or was it our trampling feet that inhibited its seed from sprouting? 

Every action has consequences, so many of which are unknown. I recall how, as a child, certain people were inclined to spray pesticides into the tall oak trees to bring down gypsy moth caterpillars. Our camp director screamed, during lunch, that by God he was not going to allow those trees to die! Our neighbor brought in a pump truck, unannounced in summer time, and sprayed his trees. I am still haunted by the overwhelming bitter smell of the pesticide, the sticky residue dripping from the trees, the dead birds and squirrels on the ground. His trees didn't die, nor did the camp's, but then, neither did the vast majority of unsprayed trees.

Each of us who is responsible for a part of the woodlands at the edge of the prairie has to choose for ourselves whether to act, or look away, to spray herbicides and trample, or do nothing. There is no mandate, we operate independently of our neighbors and yet nature cares little for these arbitrary boundaries.

I am inclined to act, yet feel overwhelmed by the magnitude of what is necessary to be effective. We hesitate to spray herbicide, usually in two or more applications, but pulling is incredibly time consuming, physical and often, incomplete. Should we adjust to the new, simpler woods, make peace with the knowledge that we brought this thicket on ourselves? Could there be a middle ground where buckthorn and garlic mustard and all the others are accepted to a degree, where we do not look away but effectively manage the woods?

In This Cornahh -Garlic Mustahhd!

The fight against garlic mustard, Alliaria petiolata, will be a long one. Above, you see a partially cleared area to the east of the drainage stream and an uncleared zone to the west (right side). Below you see the waterway and woods we are trying to protect.

Jewelweed, Impatiens capensis, is a native inhabitant of this part of the woods but comes to rise late as it is quite frost intolerant. It's also a lovely plant in leaf, flower, and remedy. I love this part of the woods and do not want to see it over run, but that's what's in store without our management. Sadly, we'll have to create some compaction damage in order to pull garlic mustard. With that in mind, keen observation is drumming up some techniques that keep us pulling only once a year until the seed bank is exhausted. This area has now been completely cleared (but not of buckthorn, another day).

In all, we cleared about 1 acre of garlic mustard. That's a drop in the bucket, but we had to start somewhere. Above, you see it gaining a foothold among our rare wild-growing ferns. Garlic mustard is a biennial that outcompetes everything around it by growing before winter loses its grip. It also leaves chemical compounds that help establish its foothold.

From Wikipedia:
"Garlic Mustard produces allelochemicals, mainly in the form of the cyanide compounds allyl isothiocyanate and benzyl isothiocyanate,^[16] which suppress mycorrhizal fungi that most plants, including native forest trees, require for optimum growth.^[17] However, allelochemicals produced by Garlic Mustard do not affect mycorrhizal fungi from Garlic Mustard's native range, indicating that this "novel weapon" in the invaded range explains Garlic Mustard's success in North America.^[18] Additionally, because white-tailed deer rarely feed on Garlic Mustard, large deer populations may help to increase its population densities by consuming competing native plants. Trampling by browsing deer encourages additional seed growth by disturbing the soil. Seeds contained in the soil can germinate up to five years after being produced (and possibly more).^[19] The persistence of the seed bank and suppression of mycorrhizal fungi both complicate restoration of invaded areas because long-term removal is required to deplete the seed bank and allow recovery of mycorrhizae."

And above, another reason it's so pernicious. Like the monster in a movie, just because you gave it a good whack doesn't mean its dead! All my piles of garlic mustard turned their growing tips upward after a day or so, continuing to flower and set seed! You cannot compost these unless it is well before, well before, flower formation. Don't think chopping them up is good either, and stay clear from the weed whacker if you find yourself falling behind -it will just distribute the very viable seed. I found that even picking up piles created great opportunities for the seed heads to get stuck to my muddy shoes and transport elsewhere.

I am no fan of Monsanto, nor pesticides of any kind. That said, I am considering the use of glyphosate during a dry period of early or late winter when there is no snow and the garlic mustard is green. It is about the only thing that is up at the time and from what I understand (considering how everyday the use of this product is on our food crops) it will have little obvious effect on plants dormant at that time. I will test this theory, and be considerate as can be.

I am sad to say I did not get to every major patch of garlic mustard growing this year. The back swale comes to mind, and everything over the bridge was completely untouched by us. Now that the woods are summering, the mosquitos prevalent, and the seed heads likely to break, I may just leave the thousands that remain until autumn.

Spring Ephemera

Too much woods and too little time.

I am excited to find ordinary ramps, Allium tricoccum, the kind that grows in dense matts, has larger leaves, and reddened stems in a far corner of the woods, just below the road, next to an ash tree, Virginia Wetleaf and Wood Anemone. I've looked in all corners by this time, and this appears to be the only patch making the common ramp the rarer of the two in our woods!

In other ramp news, this patch of A. burdickii appears to have been chomped by deer with good taste.

At the edge of the north slope, Large-flowered Bellwort, Uvularia grandiflora. Could its wilted appearance be a defense against browsing deer?

According to Illinois Wildflowers: "The presence of this plant in a deciduous woodlands is an indication that much of the original ground flora is still intact." That's good news, but it's not the whole story in our woods. I do think this bellwort is another worth trying to cultivate.

The quantity of Viola species makes identifying them a hassle, at least for busy guys like me. They grow everywhere -in the lawn, in the gardens, in the woods, on the old farm roads and paths. They are lovely. This one might be Northern Bog Violet, Viola nephrophylla.

We have blue, white, lavender, purple and yellow violets growing all around. Above, Downy Yellow Violet, Viola pubescens.

Jack In The pulpit, Arisaema triphyllum, are coming up throughout the woods.

Jack can change to Jackie from year to year, depending on reproductive success in the prior year. According to Minnesota Wildflowers: "Males tend to be smaller than females and have a small hole at the bottom of the spathe which allows pollinators to escape (with their pollen) more easily. Female plants lack the hole and pollinators are more likely to become trapped, better ensuring successful pollination." Pollination leads to the multicolored fruit seen here.

Wood Anemone, Anemone quinquefolia, growing in the drier, upslope woods near the old tractor road. 

In another, forgotten location, a pink variety of Wood Anemone.

I spotted this from across the bridge. Lousy phone photo, but maybe you can help ID it. The leaves are reminiscent of Red Elderberry. It is a pretty weak specimen, looks to be damaged by limb-fall, and is growing under a canopy of cottonwoods.

Walking the old tractor road, pulling buckthorn, I leaned in to pull this one until my vision kicked in to halt me.

A nest of baby spiders, no idea what kind, but possibly an orb weaver type. An ephemeral of another kind -off into the world younglings, and do your good work.

__________________

The greatest, visible threat to the woods and its ephemerals is the invasion of the biennial herb Garlic Mustard, Alliaria petiolata, and the shrub or small tree known as Common Buckthorn, Rhamnus cathartica.

In this fine looking scene it is easy to forget that it is greened with an army of mustard only a week away from blooming. I've begun pulling it out as I walk through the woods, but this process eats time quickly and there is always more mustard to be found! I may have to wholesale cut them back with a weedeater or sickle just to stem the tide. As is so often the case with strong weeds, these break at the root only to regrow. Any gardener knows what happens then -it simply grows back even faster, setting flower and seed on a smaller, harder to pull plant. Garlic Mustard has a 5-7 year seed bank, but it should get a little easier each year.

Garlic Mustard is bad, but nothing in our woods is as challenging as Buckthorn. Every fallen tree is another opportunity for this plant. While this corner has been a Buckthorn stronghold for many years, it really took off after a great White Oak toppled in a bad thunderstorm four years ago. It now grows on the trail as much as to the north and south of the trail.

Buckthorn can become an impenetrable thicket above and below ground. A tangle of fibrous, tough roots chokes out plants below the soil and a dense cover of leaves smothers ephemerals and low growing shrubs from above. Although many young saplings die back in winter, each sprouts new leaves from the lower stem and ground each spring. I hand pull up to 1/4-inch diameter twigs in advancing areas, but in established "groves" larger shrubs and twigs must be dug out, doing further harm to the plants that may have coexisted thus far.

Within the great wetland, large Buckthorn grow on the slightly higher ground occupied by the beautiful Red Osier Dogwood and Pussy Willow. Its seed is dropped by perched birds, which then sprout and overtake the dogwoods and willows. I haven't seen it to go head to head with cattails or get a sure foothold in the ephemeral pond of the back swale. In fact, after last year's flooding, I see many small upstarts didn't sprout this spring. Can we flood them out? If not water, then I love the idea of burning them out, although this would be hard to do safely.

Forestry experts, ecologists, park managers, and many others often discuss the advancing Buckthorn and Garlic Mustard as an ecological issue, a problem of "native" forest habitat. Surely it is, but for me this is a gardening problem. Intellectually, I agree with the experts, but my motivations are less than pure. I simply don't like the look of a Buckthorn monoculture and prefer to be able to see through the woods. I like surprises, yet Buckthorn and Garlic Mustard offer none other than the ability to show up in a previously unheard of location. It may be that ecological problems are more easily taken on when we believe we act for our own interest.
